That looks like a good start and something worth playing with. However, if I completely screw up the Cisco router settings is there a quick and easy way to reload the last known good configuration without having to power cycle the router?

you could save the current / old configuration to flash:<br />
<br />
<b>copy run flash</b><br />
<br />
you should then be asked to enter a file name to save the configuration under...if i remember correctly.<br />
<br />
and then if things go bad issue the following command:<br />
<br />
configure replace flash:&lt;file name&gt;<br />
<br />
This should replace the running configuration. However I have had varied success with this as it seems on routers the configuration is only merged with the existing configuration. &nbsp;I have had no issues with using this on switches.

I'm new to Cisco routers and to RADIUS services. I have no idea what I'm supposed to do. I've installed the Internet Authentication Service on the server but that's as far as I've got. I have no idea how to configure IAS on the Windows Server and no idea how to configure the Cisco router to use it when it is configured. Can anyone offer any help?

A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.

A virtual private network (VPN) is a network that uses a public telecommunication infrastructure, such as the Internet, to provide remote offices or travelling users access to a central organizational network securely. VPNs encapsulate data transfers using secure cryptographic methods and other security mechanisms to ensure that only authorized users can access the network and that the data cannot be intercepted.
